we have an old HD16a (lol they are all old..) anyway when we bought it I talked to the owner who had it before the guy we got it from. He told me about a screen/filter under the seat (access from bottom) that you need to clean for the hydraulics for the brakes. Some times when I push the brake peddle to steer its like pushing a car brake peddle, just like butter, but other times it is like the flinstones and I feel like I have to push through the floor board and it really doesn't work., Ive checked the fluid in both hydraulic reservoirs and we replaced one of the pumps.
Does anyone have a pic of this elusive screen? I've looked numerous times to no avail...

i have a 16A. there is no screen unless someone added it. in fact there is no filter of any kind on the early tractors, later ones had a filter on each pressure line coming off the pump. there is only 1 reservoir and its in the engine compartment. mine is 4715 a '58, one of the last ones before the change to hyd wet brakes.
you can look at the parts book here for 16A. A is 6 speed manual trans. some later ones had a pump on trans for oil pressure but that doesnt affect brakes. perhaps you have a later model?

that pump that drives of crank with reservoir in grill is for blade control

The screen side bottom transmission is for power shift transmission

Well, he told me there was a screen and when he cleaned it the dozer braked/turned that much better. I was really hoping it was true !! Lol

I know this post is old however I have just taken possession of a 61 HD16DA. Hydraulic blade. My steering with just the hand levels and moving without a load like moving from one place to the other in the field, is almost non existent. I have to use the brake pedal with the steering lever to make any adjustments while moving. I have not tried with a load yet as I just got the dozer this past Saturday delivered and am adjusting tracks and fluid levels and grease first.
Did you ever find out any more on your steering clutches?
